Completed vs. invoiced jobs (or invoiced jobs as a percentage of completed jobs) is a crucial financial metric for field service organizations. It means what you might think: you have a number of jobs completed (services rendered), but some of those jobs haven't been invoiced (you have not been paid).In a perfect world within your FSO, this ratio of completed to invoiced would always be 1:1. Whenever a technician completes service, he or she would invoice the client on-site. The client might not pay right away, but at least the invoice is out there.
